IWZE'LHQD 0E GHGING CELLULQSE BOILERS AND THE IJKE AND DEVICE ADAPTEDTHEREFOR.

' Application filed February a, was, Serial No. 86,824., and in sweaenDecember 11, 1925.

For the chargingot cellulose boilers, diftere'nt methods have beentried, such as stamping, blowing in air et-cetera, in order that thewood chips might be more compact in the boiler than they would be ifthey only fell 'down of their own weight. According tothe presentinvention a jet of steam is used for inserting the ,wood chips into theboiler. This steam is condensed in the boiler andconsequently no suctionis required. At the same time that the steam moves the chips, it effectsa considerable saving in the time of steaming.

An example of the'manner of process will be more closely described inthe following with reference to theaccompanying drawing, which shows asuitable device for the procedure in Fig. 1 seen from the side and inFig. 2 seen from above.

An open cylinder 2 is arranged for the insertion of the wood chips intothe boiler. The cylinder is provided at the top with a flange 1, whichis arranged on some appropriate support to hold up the cylinder insuitable position in relation to the feeding hole of the boiler. Anencircling pipe 3 rests on the flange, which pipe is joined to a certainsteam source situated outside the boiler. From said pipe 3' six smallerpipesa, 5 which pass through the flange go downwards, and open outinside the cylinder atdifi'erent levels. The lower parts of the pipe arebent in the same direction in such a way that the jets of steam aredirected slantingly downwards. The pipe, if one so desired it, couldnaturally be altogether arran ed inside the cylinder. 7

E lie wood chips fed to the cylinder are carried by the jets of steamand hurled by these in whirling motion down into the boiler.

'llhe invention is not limited to cellulose boilers but may also be usedfor other devices for similar purposes.

Hav ng now described my invention, what I claim asnew and desire tosecure by Let'- ters Patent is:

1. A method for charging cellulose boilers and the like characterized inthat the charge is inserted into the boiler by means of steam which isforced into it.

2. A method according to claim 1, characterized in that the charge isinserted into the boiler by means of several jets of steam directedslantingly downwards.

3. A device for charging cellulose boilers and the like consistingL of acylinder adapted to be joined to the oiler, a pipe for supplying steam,and other pipes opening at one end into the cylinder and at the otherend communicating'with the steam-supplying pipe.

4. A device according to claim 3, characterized thereby, that thepipesopen in slanting direction downwards at different levels in thecylinder.

5. A device according to claim 3, characterized in thatthe cylinder isprovided at the topwith a flange ada ted to carry the cylinder, and thaton this ange a steam pipe is arranged from which the pipes opening intothe cylinder go.

In Witness whereof, I have hereunto signed my name.
